    Open loop just requires a little more attention - personal preference.

    I have 2 Sea Doo two smokes which are open loop, I guarantee you my next skis will be closed loop. Hope this helps

    They are correct, it does leave the engine open to corrosion and that's the reason BRP designed a closed loop system.
    If you run open you just have to be sure and flush that bad boy properly after every ride and hope for the best.

    really who? ive ran open loop for 3 years. As long as you use anodes at the open loop plate and in the intercooler and flush after every ride its not a problem.

    There are several reasons to stay closed loop. One is engine wont overheat as easy when you run it in shallow water only the exhaust will be in danger. Two water temp can be controlled tighter and performance will be more consistent. Three when water gets over 140 degrees it starts to deposit material like calcium and salt on surfaces inside the water jackets. I doubt most of us would need open loop cooling.

    Not trying to argue but if you search here you will find several LENGTHY threads about all of the issues.

    Im sure you have enough experience to deal with the issues some of us less talented members do not. It just seems like a waste of money and time when you can use a heat exchanger and get the benefits of a perhaps better rideplate..

    Really, I have over 100 hrs of open loop salt water riding and have had the motor apart and the head off with no calcium deposits at all. Everything looks pristine. The only point of contention is where the oem thermo housing was. The shaft that holds the impeller is steel and will show signs of slight surface rust. However there are many well documented ways to prevent this. My water temp is maintained @ 160 deg. no problem.

    I am not being argumentative. I am simply stating the facts as I know them. Im not using second hand info. Or guessing because i heard something or someone told me something.
